The invention comprises a plurality of improvements in pusher ram construction for use in coke ovens and the like. These improvements include: (1) two separate "heat spring" arrangements for absorbing both heat and mechanically induced stress in the web portion of a pusher ram, while maintaining desired rigidity; (2) five different constructions for relieving stress developed in welds in pusher ram beam members and/or welded connections between the web portion of a pusher ram and adjacent beam members; (3) two unique girder assembly arrangements to facilitate component replacement; (4) an improved girder web construction for accommodating decarbonizer piping or the like; (5) several useful advancements in ram head design and construction; (6) special heat shield applications for pusher rams; and (7) improvements in ram girder "bull nose" construction.
